Seattle Pottery Supply/Northwest Ceramic Supply, offers one of the most complete selectiions of chemicals and raw materials for the entire ceramic spectrum, including pottery, ceramics, glass and enameling. Descriptions are provided for some, but certainly not all of the chemicals on our price list. If you need something and can't find it on our lists or on our price lists, call us. Chances are we have the material or can find it for you.

Many ceramic materials are TOXIC. We at SPS feel that the safest course is to consider all materials worked with as toxic. Before you use any raw material, read up on it. Remember that combining two different items that are perfectly safe may result in an extremely toxic product. Use good common sense and be safe. A good industrial grade respirator and rubber gloves MUST be used. Do not eat or smoke with working with chemicals! Good habits of cleanliness, including frequent changes of contaminated clothing, can keep your studio a safer place.

The companies that supply us with our raw materials are the best in their fields. However, many of the materials we supply are natural products and may vary. We urge you to test each material when purchased. We can't make any warranty concerning these materials since the control of them is out of our hands. Again, test each raw material to make sure it will do what you expect before committing to a large batch.SPS is dedicated to ongoing safety research and awareness.
